The Three-striped Warbler generally has a very distinctive head pattern, although there is some variation in this over the species’ very broad range and among the 12 recognized subspecies. Most (but not all) possess striking black ear coverts, contrasting with the broad pale supercilium, with black lateral crown stripes, and a paler (sometimes yellowish) central coronal stripe. Three-striped Warbler is distributed from Costa Rica south to south central Bolivia, and east to western Venezuela. Throughout, it inhabits montane and submontane forests between 300 and 3000 m, with one record from very close to sea level. Like many other Basileuterus, in the non-breeding season groups of this species frequently join roving mixed-species foraging flocks, which travel rapidly through the understory.
